An old or weak torque box can mean body flex or frame twisting which can do serious damage to your Mustang. If you need to replace the entire torque box, we recommend this one-piece style reproduction. Made from high-quality 14-gauge steel.

RIGHT AND LEFT TORQUE BOXBOUGHT BOTH TO GO WITH FLOOR PAN KIT. SEPERATED THEM FOR EASE OF INSTALLATION. BE SURE TO COAT THE INSIDES WITH SOME KIND OF RUST PREVENTATIVE. I USED ZINC RUSTOLEUM. CAN USE WELD THRU PRIMER ALSO BUT IT IS MORE EXPENSIVE.THEY ARE BASICALLY THE SAME THING.

By Bill Tumas:
We're here with a replacement front torque box for your 64-1970 Mustang Coupe or Fastback. Ford realized the benefit of the front torque boxes in convertibles and use them since 1965. By 1967, they had a driver side torque box in the Mustang, by 1968 all three body styles benefited from both front torque boxes. Even though your 65-66 Coupe never came factory with torque boxes, we strongly suggest adding them to your restoration to increase the strength of your front end. Our torque boxes are made of heavy gauge steel and they come pre-welded so they're ready to install. Here you can see the torque box installed on this 1965 Mustang Coupe; it's going to weld between your frame rail and your rocker to increase the strength of the front end of your car. Whether or not your Mustang came with torque boxes from the factory, when you're doing your restoration, we highly suggest adding a set to your build.
